The Best Sleep Mask for Side Sleepers: What to Look For

Side sleeping is the most common sleep position, yet most sleep masks seem designed for people who lie perfectly still on their back. Roll over and the strap twists, the mask rides up, or it presses into your eye. Here's what to look for if you sleep on your side.

Why most sleep masks don't work for side sleepers

• Thick side panels push into your temple and cheek against the pillow.
• Flat fabric presses directly on your eyelids, which gets uncomfortable fast.
• Thin elastic straps roll and dig in behind your ear.
• Gaps around the nose let light leak in as soon as the mask shifts.

6 things to look for in a side-sleeper sleep mask

1. Slim, low-profile sides

The section between your eye and ear takes the most pressure. A mask that thins out at the sides sits flatter against the pillow.

2. Contoured eye cups

Moulded eye cups leave a pocket of space over each eye, so nothing presses on your eyelids and you can blink freely.

3. A wide, adjustable strap

A broad, soft strap spreads pressure and is less likely to twist. Adjustability matters because a mask that's too tight is as bad as one that's too loose.

4. A nose bridge that seals

Most light leaks happen around the nose. A soft, shaped nose section blocks this without pressing.

5. Gentle weight

A lightly weighted mask settles into place and is less likely to drift when you move. Many people also find the gentle pressure comforting.

6. Breathable, washable fabric

Choose a fabric that feels comfortable for you and follow its care instructions. If a mask feels hot, tight or irritating, remove it and reassess the fit.

Our Weighted Sleep Mask was designed around exactly this problem: a contoured shape that stays put when you turn onto your side, with gentle weight to keep it settled.

Tips for sleeping on your side with a mask

• Test the mask with your usual pillow and position; adjust the mask gently rather than changing pillow height to force a fit.
• Position the strap above your ears rather than over them.
• Put the mask on before you lie down, then adjust once you're settled.
• Give it a few nights. It takes a little time to get used to sleeping with anything on your face.

Frequently asked questions

Is it OK to wear a sleep mask every night?

Yes. For most people, wearing a clean, comfortable sleep mask nightly is fine. Wash it regularly and stop if you notice any irritation.

Why does my sleep mask keep falling off?

Usually the strap is too loose or too thin, or the mask is too bulky at the sides. A contoured, lightly weighted mask tends to stay put better.

Can a sleep mask help with early summer sunrises?

Yes. In June the sun can rise before 5am in parts of the UK, and a good mask blocks that light completely.
